Conservation of resources is the ethical use and protection of valuable resources, such as trees, minerals, wildlife, water and others. It focuses on maintaining the natural world in order to protect the sources of resources.

The Earth has several natural resources, including oil, water, gas, animals, minerals, soil and air. Humans depend on these resources in order to survive.
